5.6.3 Conformation and crystallinity

If there are key connections between the chain configuration and crystallisation, you might also expect some more subtle effects from rotation about chain bonds. After all, polymer chains must be able to twist into the regular conformation demanded for crystal structures (Figure 57(a)). And what influence will rotation have on

5.6.2 Structure and crystallinity

In addition to the structural constraints mentioned in Section 2, where tacticity and geometrical isomerism control whether or not a polymer chain can crystallise, molecular mass and copolymerization are other important variables which can influence crystallising properties. A related effect is plasticization where a low molecular mass mat

5.6.1 Morphology of polymer crystallites

The fundamental unit of structure formed by crystalline polymers which is accessible using the optical microscope is the spherulite. Isolated spherulites are formed easily at relatively slow spherulite growth rates such as those exhibited by polypropylene and isotactic polystyrene. Unlike aramid fibres where the degree of crystallisation is close to 100 per cent (Author(s): The Open University

5.6 Crystallisation of polymers

The major benefits of crystallisation of chain molecules to end users are:

  1. since Tm > Tg, the maximum service temperatures are higher than with amorphous polymers;

  2. above Tg , the modulus of a crystalline polymer is higher than that of an amorphous polymer owing to reinforcement and physical crosslinking of the amorphous matrix by the crystallites.

Both effects are
